Tomorrow the moon will be putting on quite a show. Much of the world will get to see not only a blue moon and a super moon, but also a total lunar eclipse, all rolled into one. That hasn’t happened in 35 years and it won’t happen again until 2037. The eclipse will be visible best in the western half of the U.S. and Canada, but the U.S. East Coast will be out of luck; the moon will be setting just as the eclipse gets started. A blue moon is the second full moon in a month. A super moon is a particularly close full or new moon, appearing somewhat brighter and bigger. A total lunar eclipse – or blood moon for its reddish tinge – has the moon completely bathed in Earth’s shadow.
